Reminds me of a C++ codebase I once had to inspect that was entirely written as if it were written in Java. With camelcase naming for everything, getters and setters for every class variable, interfaces everywhere.

It also assumes all reads and writes are volatile. In the real world, threads can witness out-of-order execution in different threads.

All of the above

From the wiki page:

"In 2018, professors Alan Benson, Danielle Li, and Kelly Shue analyzed sales workers' performance and promotion practices at 214 American businesses to test the veracity of the Peter principle. They found that these companies tended to promote employees to a management position based on their performance in their previous position, rather than based on managerial potential. Consistent with the Peter principle, the researchers found that high performing sales employees were likelier to be promoted, and that they were likelier to perform poorly as managers, leading to considerable costs to the businesses.[15][16][2]"

Surprises me to see I'm the first comment here to say: I just use GPT4 for this. Works perfectly, even for getting the Latex source of a formula you only have a screenshot of.

Probably quite the overkill in terms of energy efficiency for just image to text, but I only need this like once every two weeks or so.

In the city where I live, also in the Netherlands, we had multiple of these but all of them got converted back to normal intersections with traffic lights and it has been a huge improvement.

Brings back high school memories when we used to shutdown peoples mIRC client with a special message that you could send as a personal message to them.

I don't know it anymore but I remember it started with a whole bunch of aaaaaaa, but also included other characters. The beauty is the attack left no trace at all, so they never knew what hit them.

There was a company in the Netherlands, can't seem to find the name right now, that rented out GPU clusters as central heaters, while using the GPUs to mine crypto. I believe they went backrupt during the whole crypto crash and energy crisis.

Does anyone happen to know of a similar tool that can compare two codes for semantic similarity?

It's incredibly useful if you have many threads that produce a variable number of outputs. Imagine you're implementing some filtering operation on the GPU, many threads will take on a fixed workload and then produce some number of outcomes. Unless we take some precautions, we have a huge synchronization problem when all threads try to append their results to the output. Note that GPUs didn't have atomics for the first couple of generations that supported CUDA, so you couldn't just getAndIncrement an index and append to an array. We could store those outputs in a dense structure, allocating a fixed number of output slots per thread, but that would leave many blanks in between the results. Now once we know the number of outputs per thread we can use a prefix sum to let every thread know where they can write their results in the array.

The outcome of a prefix sum exactly corresponds with the "row starts" part of the CSR sparse matrix notation. So they are also essential when creating sparse matrices.
